2 3/4 + x +3 1/2 = 10
a. 3 3/4
b. 4 1/4
c. 4 3/4
d. 5 1/4

The answer should be A) 3 3/4.

convert 2 3/4 to improper fraction

simplify 2 * 4 to 8

simplify 8 + 3 to 11

convert 3 1/2 to improper fraction

simplify 3 * 2 to 6

simplify 6 + 1 to 7

simplify 11/4 + x + 7/2 to x + 25/4

subtract 25/4 from both sides

simplify 10 - 25/4 to 15/4

x = 15/4 but the choices are mixed fractions so lets simplify 15/4 and we get 3 3/4 since 5/15 = 3.

In decimal form its 3.75.
